I have a buddy who released something similar to this a little over a year ago called "The Carousel" (https://itunes.apple.com/us/app/carousel-slide-projector-for/id572401095?mt=8 https://itunes.apple.com/us/app/carousel-slide-projector-for...). It's complete with the old slide projector sounds and slide replacement animations (iirc). It sources the gallery images from Instagram. While being a standalone ipad gallery app, it can also be tethered with apple TV to make your ipad act as the slide projector by mock-projecting the gallery on your TV.
